The tides are the result of the rotation of the Earth and the whirlpools. There is a strict pattern; tides are formed, not across the coast of the seas and oceans, but only on those coasts where the high angular velocity of the currents. And the higher the velocity of currents, the higher the amplitude of the tidal wave. On the rectilinear coasts, where the currents do not have angular velocity, tides and ebbs do not form. The waters of lakes, seas and oceans of the northern hemisphere rotate counterclockwise, while the waters of the southern hemisphere rotate clockwise, forming giant whirlpools. As is known, everything that rotates, including whirlpools, has the property of a gyro (yule) to maintain the vertical position of the axis in space, regardless of the rotation of the Earth. If you look at the Earth from the side of the Sun, the whirlpools, spinning with the Earth, capsize twice a day, thanks to which the whirlpools precess (swing by 1-2 degrees) and reflect the tidal wave around the perimeter of the whirlpool. http://img-fotki.yandex.ru/get/9804/7837959.21/0_f6015_1eb816e5_orig The waters of the White Sea rotate counter-clockwise, forming a huge whirlpool-gyroscope, which, precessing, reflects a tidal wave along the entire perimeter of the White Sea. A similar pattern of tides and ebbs is observed in all lakes, seas and oceans. http://tapemark.narod.ru/more/22.png The waters of the Mediterranean Sea rotate counter-clockwise, forming tides, 10-15 cm high. But in Gabes Bay, "what?" Off the coast of Tunisia, the height of the tides reaches three meters, and sometimes more, and this is considered one of the mysteries of nature. But at the same time, in the Bay of Gabes the whirlpool turns, precessing the reflecting additional tidal wave ?. A tidal wave in the Amazon River creates a huge planetary maelstrom a few thousand kilometers in diameter, rotating between South America and North Africa, embracing the mouth of the Amazon River. The scheme of motion of a tidal wave, along the perimeter of the North Atlantic planetary maelstrom. The length of the tidal wave depends on the diameter of the whirlpool. And the height of the tidal wave depends on the speed of rotation of the whirlpool of the orbital velocity of the Earth, and the time of the tilting of the whirlpool (12 hours). A = V1 • V2 / t where: A is the amplitude of the tidal wave (precession angle). V1 - rotation speed of the whirlpool. V2 is the orbital velocity of the Earth. t - the time of tilting of the whirlpool (12 hours). The vortex theory of tides can be easily verified from the connection of the height of the tidal wave with the rotation speed of the whirlpools. The height of the tidal wave can determine the location of the whirlpools. Drawing on a map of the depths and currents of the seas and oceans.
